Abstract

The article examines the motion caused by the explosion of a spherical charge in elastoplastic continuous media. When a charge explodes, it is assumed that the charge instantly turns into a high-pressure gas without changing its volume, and this gas spreads into the environment, forming a shock wave with spherical symmetry. Taking into account the presence of tangential stresses in inclined areas, equations of one-dimensional dynamic motion of soil are derived, according to which the patterns of propagation of shock waves in soil massifs during an explosion with spherical symmetry are studied. To find the limiting state of the soil, the Prandtl plasticity condition was used, and also when determining the radial stress at the shock wave front, experimental dependencies between and were used. The general solution of the problem and the necessary values for its numerical solution in the case of constant density on the shock wave are given.
